提问： 王文静老师，我想问个关于',＋doing'和and的问题，下面整理的问题，我都是在这个地方出现犹豫或者选错,真的是屡做屡错，字有点多，麻烦老师看下啦 Q849是一个句子＋doing的结构，letting引导的是一个对前面动作进行补充解释的动作，与前面的句子是有关系的，所以不能用and去连接，因为and连的是相互独立的没有关系的动作或者事情 Q851 gives mouth和displace grasses并列，造成的结果用rendering作为引导跟在后面，也算是补充解释 Q862也是句子＋,＋doing作为前面一整个句子的补充解释 但是问题来了，Q858 B选项，south are hunting crops and therefore raising这个为什么能对? and不是连接相互独立的两个部分吗，那therefore就是表示因果关系的啊，这不是矛盾了吗，还是这道题目主要的考点不在这里而在于平行，所以有瑕疵也是可以容忍的? Q 865虽然正确选项B可以通过其他考点排除，但是'overcompensating，growing'为啥不好呢，growing an extra one or two不能作overcompensating的补充解释吗，这里有必须选and不选doing,doing的理由吗？

( Monitoring heart patients' exercise as well as athletes excersing, is now done by small transmitters broadcasting physiological measurements to nearby recording machines. ) A. Monitoring heart patients' exercise as well as athletes excersing, is now done by small transmitters broadcasting physiological measurements to nearby recording machines. B. Monitoring the exercise of heart patients, as well as athletes excersing, is now done by small transmitters broadcasting physiological measurements to nearby recording machines. C. Small transmitters broadcasting physiological measurement to nearby recording machines are now used to monitor the exercise of both heart patients and athletes. D. Broadcasting physiological measurements to nearby recording machines, small transmitters are now used to monitor heart patients' exercise, as well as athletes exercising. E. Both athletes exercising and heart patients' exercise are now monitored by small transmitters broadcasting physiological measurements to nearby recording machines. 答案是C，错选了E。排除C的原因是感觉主语很长，头重脚轻。第一遍看原文的时候感觉exercise和exercising不平行，但是每个选项读下来发现都是这个形式，（当时没有注意到C的形式）于是就认为这个可能不是考点。E的错误是exercise和exercising吗？麻烦老师讲解。

( Even though its per capita food supply hardly increased during ) two decades, stringent rationing and planned distribution have allowed the People’s Republic of China to ensure nutritional levels of 2,000 calories per person per day for its population. (A) Even though its per capita food supply hardly increased during (B) Even though its per capita food supply has hardly increased in (C) Despite its per capita food supply hardly increasing over (D) Despite there being hardly any increase in its per capita food supply during (E) Although there is hardly any increase in per capita food supply for 错选了E，答案是B。排除ABCD是因为代词its，前半句说了its，后半句没有第一时间解释its是指谁。尽管觉得E也有不妥之处，E的any increase应该是名词吧？副词hardly修饰名词也不对吧？麻烦老师讲解。

During the recession of 1973, home mortgage foreclosures resulted in tens of thousands of Americans being evicted from homes ( that they can ) no longer afford monthly payment. A. that they can B. that they could C. on which they can D. because they can E. for which they could 错选了B，答案是E。不明白that和for which的区别，麻烦老师讲解。

In three centuries -from 1050 to 1350-several million tons of stone were quarried in France ( for the building of eighty cathedrals, five hundred large churches, and some ) tens of thourands of parish churches. A. for the building of eighty cathedrals, five hundred large churches, and some B. in order that they might build eighty cathedrals, five hundred large churches, and some C. so as they might build eighty cathedrals, five hundred large churches, and some D. so that there could be built eighty cathedrals, five hundred large churches, and E. such that they could build eighty cathedrals, five hundred large churches, and 把句意理解错了，选了D，答案是A。当时想的是一些石头被挖掘了在法国，后面应该是：导致在法国建立了多少教堂。排除BCE是感觉they指代有问题。没选A是不知道原文说的是这些石头用来建立教堂，而且后面有个some，不能理解some tens of throusands of。麻烦老师讲解。

While larger banks can afford to maintain their own data-processing operations, many smaller regional and community banks are finding that the ( cost associated with ) upgrading data-processing equipment and with the development and maintenance of new products and technical staff are prohibitive. A. cost associated with B. costs associated with C. costs arising from D. cost of E. costs of 这道题选了A，答案是B。上次答疑英老师说cost是不可数名词，不明白为什么选B。做题时感觉应该不是根据后面的谓语are来判断，因为谓语动词前面and连接了几个并列成分。现在review时不确定这些并列成分全都是修饰cost的，还是cost的并列。麻烦老师讲解。

Pensions are now viewed as a deferred payment of salary, money ( a worker is compelled to put away to take care of one's ) later years. A. a worker is compelled to put away to take care of one's B. that a worker is compelled to put away to take care of oneself in C. a worker is compelled to put away to take care of oneself in D. workers are compelled to put away to take care of them in E. workers are compelled to put away to take care of themselves in 这道题做对了，选E。但是做题过程不对，take care of后面应该是反身代词，所以A D排除，B C E的区别是单复数，不知道突破口在哪，只是感觉如果B对，C肯定也对，that应该可有可无，不足以影响对错，所以选了E。其实这道题不太明白，麻烦老师讲解。

Many investors base their choice ( between bonds and stocks on comparing bond yields to ) the dividends available on common stocks. A. between bonds and stocks on comparing bond yields to B. among bonds and stocks on comparisons of bond yields to C. between bonds and stocks on comparisons of bond yields with D. among bonds and stocks on comparing bond yields and E. between bonds and stocks on comparing bond yields with 选项明显的差距就是between and以及compare with，所以选了E，答案是C。麻烦老师讲解一下comparing和comparisons of的区别。

( The rising of costs ) of data-processing operations at many financial insititutions has created a growing opportunity for independent companies to provide these services more efficiently and at lower cost. A. The rising of costs B. Rising costs C. The rising cost D. Because the rising cost E. Because of rising cost D E 没有主语，排除。谓语是单数，B 排除。A是成本的上升，C是上升的成本，句意是创造了更多的机会去提供服务。感觉意思都说的过去，纠结好久。答案是C。做题时没有关注到后面的 at lower cost，不知道这里和前面的cost有没有关系，是否可以根据这里把A排除？麻烦老师讲解。

In December of 1987 an automobile manufacturer pleaded no contest to criminal charges of odometer tampering and agreed to pay more than $16 million in civil damages for ( cars that were test-driven with their odometers disconnected ). A. Cars that were test-driven with their odometers disconnected B. Cars that it had test-driven with disconnected odometers C. Its cars having been test-driven with disconnected odometers D. Having test-driven cars with their odometers disconnected E. Having cars that were test-driven with disconnected odometers 一遍下来读的不太懂，大致是汽车公司对O T的违法赔偿不作辩护并且同意支付多少钱关于被测试过O D 的车。 B C的代词不对，排除。看到D E直接就排除了，不懂想要表达什么，选了A。答案是D。麻烦老师讲解。
